Hello,
I would like to use Alembic to manage my Hive Metastore. I have installed,
PyHive, SqlAlchemy, and Alembic. I am able to create a functional engine
object using the 'hive' dialect in sqlalchemy, however I cannot get Alembic
to recognize this dialect. The problem appears to be a lack of a HiveImpl
class in the Alembic package. I attempted to resolve this by creating an
alembic/ddl/hive.py module and pasting the following code into that module:
from .impl import DefaultImpl
class HiveImpl(DefaultImpl):
__dialect__ = 'hive'
I simply want to be able to execute raw SQL against a Hive instance (no ORM
implementation needed) and I was hoping to use Alembic to manage the minimum
upgrade/downgrade functionality. Are there any simple edits I can make to the
Alembic source code to allow me to achieve this goal?
Thanks,
Alexander
